ULTRASAT is a scientific satellite carrying a near UV optimized (NUV; \(230-290\,\) nm) telescope with an exceptionally wide field of view (FoV) of \(200\,\) deg\(^2\) . It is led by the Weizmann Institute of Science and the Israel space agency in collaboration with DESY (Helmholtz association, Germany) and NASA (USA), and planned to be launched to geostationary transfer orbit (GTO), with operation at geostationary orbit (GEO) commencing at Q2/Q3 2025. The mission is targeting time-domain astrophysics phenomena, and is the first wide FoV telescope operating in the NUV band. For hot sources (T\(\sim 20,000\,\) K) ULTRASAT is comparable in grasp, the amount of volume of space probed per unit time[1]}, to that of the Vera C. Rubin observatory[2]}, the largest ground-based optical transient survey planned to begin operation in 2024.
